## CAD (KiCad official)

- Symbol: `GBU401G`
- Footprint: `Diode_THT:Diode_Bridge_Vishay_GBU`
- 3D model: GBU (KiCad packages3D, STEP)
- 3D model files: `gbu401g-etched.step` / `gbu401g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gbu401g.step` / `gbu401g.glb` are the bare package body.
